This inventionrelates to an attachment for use in connection with farmtractors, the primary'object of the invention being to provide a device adapted for attachment to the froht end of a tractor to be used as a mulch lifter, or to smooth the ground directly in advancev of the front wheels of the tractor, eliminating vertical movement of the tractor, caused by the tractor moving over a ridge or furrowed field.

An important object of the invention is to provide a device of this character which may be readily and easily bolted to the usual tractor frame, the device having means wherebythe' disks, sweeps or shovels thereof, may be ad- Justed vertically, to meet the requirements of use. i

With the foregoing and other objects in view, I

which will appear as the description proceeds,

struction hereinafter described and claimed, it being understood that changes in the precise emthe invention resides in the combination and arrangement of parts and in the details of conbodiment of the invention herein described may "be made within the scope of what isclaimed, without departing from the spirit of the invention. l

Referring to the drawings; Flgurel is a fragmental elevational view illustrating a tractor equipped, with a device constructed in accordance with the invention.

Figure 2 is,a fragmental side elevational view thereof, the shovels thereof having been moved to their inactive positions.

, Referring to the drawings in detail, the reference character 5 designates the usual farm 1 tractor having wheels 6, supporting the front end of thetractor. The, attachment comprises ,a frame including the supportingbars I, which are secured to the side rails of the tractor chassis, as clearly shown by Figure 2 of the drawings.

These bars I are formed with T-shaped ends or heads 8 which are secured to the bars' 9, by means of the bolts III that pass through openings in the heads 8 and extend through elongated openings ll, formed in the bars 9.

Atthe lower ends of the bars 9 arebearings l 2 in which the ends of the shaft I3 are mounted,

there being provided a cotter key M at one end of the shaft for holding the shaft 13 against movement through the bearings in one direction.

The reference character l5 designates a brace bar that extends between the bars 9 the brace bar having. downwardly extended and {portions l6 that are bolted to thebars 9, by means of the bolts HI.

Application July 26,1937, Serial No. 155,820 1 Claim. (01. 97-47) Secured to theshaft l3, at one end thereof, is an arm H, which is formed with an opening through which the right angled end l8 of the rod l9 extends, so that the rod l9 is pivotally connected with the arm II.

The upper end of the rod I9 extends through a pivoted eye member 20,.and is held within the pivoted eye member, by means of the nut 2| positioned on the threaded end of the rod IS. The reference character 22 designates a coiled spring that engages the pivoted eye member 20, the opposite end of the coiled spring contacting with the adjustable collar 23, mounted on the rod l9. Thus it will be seenthatdue to this construction, the tension of the spring 22- may be adjusted, to meet various requirements.

The pivoted'eyemember 20 is carriedat one 1 end of the arm 24 whichin turn is securedto the shaft 25 to move therewith, the shaft 25 being supported in' suitable bearings. The shaft 25 constitutes the actuating arm for actuating the rod l9, and as shown, this shaft 25 is supplied with arm 26 to which the bar 21 is connected, the

bar 21 being operated by the usual power mecha-,

nism, not shown. An arm indicated by the reference character. 28 is secured to one end of the shaft 25, and this arm has connection with the bar 29 that extends towards the rear of the tractor, and has connection with a lever not the blades from their active position as shown.

by Figure 1 of the drawings, to their'inactive positions as shown by Figure 2, it is only necessary to operate the shaft 25-to' rotate the shaft l3, moving the shaft in the desired direction.

Brace bars indicated by the reference character 32- are provided, and hold the bars 9 against rear-ward movement, under the action of the blades 3| digging into the ground surface.

Should itbe desired to raise or lower the shaft l3 tochange the depth of operation of the blades 3|,it is only necessary to loosen the bolts l0, and move the bars 9 vertically. The bolts will then be tightened and the bars 9 securely held in their positions of adjustment.

While the'blades have been described as a the bearings, spring arms carrying blades, mounted on the shaft, an arm secured to one end of the shaft, a rod connected to the free end of the arm, an operating shaft, an arm having an eye member, secured to the operating shaft, said rod extending through the eye member, a collar on the rod, a spring on the rod, one end of the spring engaging the collar, the opposite end of the spring contacting with one edge of the eye member, cushioning the movements of the rod, and means for operating the operating shaft to raise and lower said spring arms and blades.
